Newly Diagnosed Locally Advanced Breast Cancer

I needed to ask before I take drastic measures and call the clinic...but I have notoced my body has started hurting more and more but this morning I woke up and I felt like my body was ready to explode. The best way to describe it is, its a heated pain. The pain ive had is worse but its hot. Ive taken panadol and nurofen which has done nothing at all but ive checked and i dont have a fever. Any ideas what i should do? I know you all arent doctors but i wanna know if you have suggestions before i call the clinic with an SOS
